![]() You can more safely unwrap with an exclamation point within an if statement because this sound is nominally guaranteed to be non- nil in non-extreme (that is, nonthreaded) situations: if sound != nil Īlthough useful for accessing values, if-let bindings build into code structures colloquially known as pyramids of doom. It’s pretty important to check whether an item is nil before unwrapping it. In your case, a cast from a Dog to an Animal is an upcast, because a Dog is-a Animal. Upcasting is always allowed, but downcasting involves a type check and can throw a ClassCastException. ![]() The nil value is the Swift equivalent of your aunt’s home-crocheted vest with a large friendly moose decoration on it. Upcasting is casting to a supertype, while downcasting is casting to a subtype. If the value is nil, you experience a fatal runtime error-which is not nearly as fun or gratifying for your workday. If the value is wrapped (that “optional” result you just read about), the exclamation point returns the value stored within the wrapped element. This is also the most dangerous approach, and you want to generally avoid it in production code. ![]() Using type casting we check the instance that it. The simplest way to extract an optional value is to append an exclamation point: print("The sound is \(sound!)") // may or may not crash In swift, Type casting is the process in which we can convert the type of one object into another type. There isnt a way to do it in one if statement that will be runtime-safe, but there is a way. The expressive possibilities expanded in Apple’s Swift 2 update to provide greater developer flexibility. The reason your desired formulation isnt working is that youre trying to unwrap two Optionals with a single as.There are two Optionals because both the subscripting of your dictionary and the attempted cast to String return optional values. There are more ways to get at a wrapped optional value than you might expect. Swift offers a variety of mechanisms for unwrapping optionals and recovering the underlying data type stored within them. In the Swift world, it is always Christmas, and there are always presents-or at least variables-to unwrap. You cannot get to that value (in this case, "moo") without unwrapping it. This does have the same truncating effect as using init (truncatingIfNeeded: BinaryInteger). let i: NSNumber 300 let j i as Int8 // j 44. Upcasting and downcasting gives us advantages, like Polymorphism or. As Hamish and OOPer mentioned in the comments, it is now possible to cast an NSNumber directly to Int8. Up-casting is casting to a supertype, while downcasting is casting to a subtype. Wrapping means that any actual content is stored within a logical outer structure. Directly casting NSNumber with as Int8 in Swift 3.0.1 and above. Optional types always return either a wrapped value or nil.

The angle impacts the amount of coverage you'll get from the brush, with sharp slants providing more full coverage than softer angles. Sephora Collection's national artist Helen Phillips says to "to look for brushes with dense bristles" for full coverage, and "for lighter coverage, use a fluffier brush."Ĭontour brushes may have bristles that run straight across, at a single slanted angle, with a triangle right angle curve in the center, a fan appearance, or even a step-looking shape. How dense your contour brush's bristles are determined by how full or light the coverage will be, so select according to the amount of coverage you generally seek from contour. Byrdie writer Devon Hopp recommends lukewarm water for the cleaning water temperature, and to always run the water down the length of the bristles, not up. Ensure the brush will be easy to clean by choosing one that connects easily to the handle without any parts that may be tough to wash or get into. What to Look For in a Contour Brush Easy to Clean Brush HeadĬleaning your makeup brushes doesn't need to be a chore-but if a contour brush isn't easy to clean, it will be one. The Real Techniques Sculpt & Shape Dual-Ended Brush is a nice, more affordable alternative (and has the added benefit of being dual-ended). ![]() The Charlotte Tilbury Powder & Sculpt Brush and Patrick Ta Major Sculpt Contour Brush are our top two favorites, both on the slightly more expensive side but with unique shapes that make for a very versatile contour application. This particular brush is super durable, boasting antimicrobial synthetic bristles, corrosion-resistant metal on the ferrule (the part that connects the bristles and handle), and a waterproof handle.īrush Material: Synthetic Fibers, Plastic | Features: Corrosion-resistant metal on the ferrule and waterproof polymer-based handle creates durability | Cruelty-Free: Yes | Size: 175mmĬontour brushes abound, and it’s important to think about both where on the face you’ll be using it as well as with what type of product when choosing one. Plus, they’re also absolutely perfect for dusting complementary highlighter tones onto cheeks and brow bones. Espinoza adds that they’re particularly good to pair with cream formulas since they help to control exactly where you want the heavier texture of the product to go. They’re ideal for imparting sheer washes of color, perfect for someone who wants to use a contour product to create natural shading rather than dramatic sculpting. While fan brushes aren’t traditionally associated with contouring, they should be. Not the best if you want a dramatic contour color Read on for the best contour brushes for a seamless look. Our team then combined these results with our research of fan favorites plus makeup artist-recommended picks to create this list. We spent hours researching the best contouring brushes, evaluating each on size, how ergonomic it is to use, shape, angles, or taper, plus the types of bristles used and their density. ![]() “There’s a huge selection when it comes to contour brushes - different shapes, various angles and curves, and ones made for specific formulas, including cream, liquid, or powder,” explains StyleSeat makeup artist Manuel Espinoza. Just like with makeup, not all contouring brushes are created equal. And finally, once you’ve checked all those boxes, it’s time to find the right tool for the job. Next, it’s time to find your shade-another pivotal step, given that going too gray or too dark can quickly leave your skin looking muddy and streaky. (Spoiler alert: It’s not as hard as it seems, so don’t be intimidated.) Then, you need to find the right contour formulas as cream and powder can yield very different results. ![]() First, you’ll want to nail the technique.

Alternatively, contrast material clears from a segment distal to a stenosis noticeably more slowly than from a comparable segment not preceded by a significant stenosis.Ī small amount of contrast flows through the stenosis but fails to fully opacify the artery beyond.

"Unfortunately, the opposite might happen, plus it increase injury risk". "I've seen many runners buy the latest running shoes because they think it will make them faster", he says. This creates less trauma in the arches as you go through training, which means you have effective recovery. With better support, the overall strain on the foot sustained on long runs will decrease, says Shum. If you have significant foot issues, you may want to consider seeing a podiatrist, he adds.ĭon't miss What's the Difference Between Stability and Motion Control Running Shoes? These often have a measuring station for your feet that not only determines size but also whether you pronate and have a high or low arch. Instead of a straight line from the ball of the big toe back to the ankle, you may see a higher arch when looking at the inside of the foot".Īnother tactic is to visit a running shop, suggests New York-based, RRCA-certified running coach, Lawrence Shum. "You may also see structural changes at the midfoot. ![]() "This indicates your midfoot is not descending down to the surface", he says. If you're seeing mostly toes and the balls of your feet with a minimal line back to the heel, that could mean you have high arches. If you're not sure if you have high arches, Kart recommends a simple trick: wet your feet, then stand on a blank piece of paper or cardboard and step away to see your footprint. For example, doing calf raises, toe pick-ups (like picking up towels and pencils using only your toes), and foot flex-and-point sessions can improve ankle and calf strength.Īnother important strategy? Making sure you have the right shoes. That means you change your training in multiple ways to avoid injuries, such as decreasing your mileage or playing around with your stride, and Kart adds that lower-body strength training is also important so you can recruit muscles that support stability. "It's not uncommon to have outside knee pain, including lateral meniscus tears, IT band problems and lateral collateral ligament strains". "The problems can extend up the chain to the knees", says Kart. Running in shoes that don't support high arches can even lead to ankle sprains, Kart says, because of instability in the ankle joint. The result isn't great-foot pain, stress fractures, shin splints and plantar fasciitis are more likely to result. That creates an undue amount of stress throughout the foot, ankle and calf. What happens instead is that the arches and feet tilt outwards, he adds. RELATED: Nike's Most Comfortable and Supportive Shoes for Heelstrike Runners A high arch fails to absorb that shock because the arch doesn't descend normally". "The foot has two basic jobs: one is to act like a shock absorber, the other is to be a bony lever to push off from. "High arches can create problems with running and training", says doctor of physiotherapy, Jason Kart, D.P.T., owner of Core Physical Therapy in Chicago. In either case, there could be multiple factors that come into play, and your shoes can be one of them, especially if you have high arches. Or you keep getting overuse injuries-even when you dial it back on your workouts. ![]() We partner with many organizations to match our clients with mentors in their own neighborhoods.Maybe your running shoes are perfectly comfortable, but you feel like your speed, endurance and recovery could be better. Knowing that each client is different, Arches meets these young people “where they are” on the path to pro-social engagement with others. Mentors facilitate group sessions and are available for intensive support, advice, and guidance outside of the group settings.Īrches is grounded in positive youth development, an approach that emphasizes reaching young adults in their own neighborhoods and building on their strengths. To counter this harmful thinking, group sessions run in a family-style atmosphere follow an evidence‐based curriculum that relies on cognitive behavioral principles aimed at self-reflection and changing behavior.Īrches mentors are “credible messengers.” Because they often come from similar backgrounds to our clients, they can connect to our young adults and their families in ways others can’t. The thought processes that may have led to violence or crime in the past can stand in the way of finding a job, finishing school or peacefully resolving conflict today. This transformative mentoring program focuses on high-risk young people age 16 to 24 who struggle to overcome the thinking patterns and behaviors that led them to probation. The Arches program connects young adults on probation to mentors with similar life experience in their own neighborhoods. |
