I am trying to build an app where there is a premium version and a free version. When someone purchases the premium version, I want a new screen to show. How do I do this. Code import SwiftUI struct ContentView: View {     var body: some View {           VStack {     Link(destination: URL(string: "https://www.icloud.com/sharedalbum/#B0tG4Tcsmu6ATjR")!) {                 VStack {                     Image(systemName: "paperplane")                         .font(.largeTitle)                     Text("Click here to get wallpapers!")                         .accentColor(Color.white)                         .background(Color.black)                         }                     }                     }                 }             } Premium Code import Foundation import SwiftUI struct Premium: View {     var body: some View {           VStack {     Link(destination: URL(string: "https://www.icloud.com/sharedalbum/#B0tG6XBubu4jvR9")!) {                 VStack {                     Image(systemName: "plus")                         .font(.largeTitle)                     Text("Click here to get Premium wallpapers!")                         .accentColor(Color.white)                         .background(Color.black)                     }                 }             }         }     }

Trying out playgrounds for the first time and I noticed something a little odd. In the first lesson when it talks about moving byte to toggle a switch it clearly said that the light turns on when the switch is ”Open” and off when “Closed”. This seems counter intuitive to the way we would normally teach electrical theory. We would use the example of a simple electrical circuit with a light. When the switch is closed the light turns on because the circuit is complete and the light receives power. When the circuit is open there is a break in the circuit and the light can not receive power. Just wonderiong if there was a specfic reason for teaching it this way in playgrounds?

I have reached to Learn to Code 2, Chapter: Types, Corner of The World puzzle. however; I have provided a solution and the Playground did not close the puzzle, but the avatar stop moving as it meets the conditions I set!! I searched the internet and found the solution, I copied the solution, the puzzle closed!! but my solution was much shorter than the solution!! I am not sure what is wrong in my code, I have attached my code. `greenPortal.isActive = false orangePortal.isActive = false var numberOfGems = 0 var numberOfSwitchs = 0 func moveAround() {     if isBlockedRight {moveForward()} else {turnRight()         moveForward()              }     if isBlocked {turnLeft()         turnLeft()     } } turnRight() moveForward() for steps in 1...2 {     moveForward()     turnRight()     moveForward()     if isOnClosedSwitch {toggleSwitch(); numberOfSwitchs = numberOfSwitchs + 1}     turnLeft()     turnLeft() } while !isBlocked {     while numberOfSwitchs < 6 {         moveAround()         if isOnGem {collectGem(); numberOfGems = numberOfGems + 1}         if numberOfGems == 6 {greenPortal.isActive = true}         if isOnClosedSwitch {toggleSwitch(); numberOfSwitchs = numberOfSwitchs + 1}         if isOnOpenSwitch {greenPortal.isActive = false}     } }

UIVisualEffectContentView.contentView.addSubview appears to be actually trying to add the sub view to the parent UIVisualEffectView in Swift Playgrounds. Code that works fine in an actual iOS app causes Swift Playgrounds to produce error: "Do not add subviews directly to the visual effect view itself, instead add them to the -contentView." Except that is exactly what the code is doing "blur.contentView.addSubview(vib)" So the internal implementation in Swift Playgrounds must be doing something wrong. Again the same code works fine in an iOS app.

I'm in the last task befor the array chapter, with creating my own world.No I'm facing the problem the the platforms do not react on the platformlock.my code is locking that way:world.place(PlatformLock(color: green), facing: west, atColum: 7, row: 6)world.place(Platform(onLevel: 2, controlledBy: PlatformLock(color: green)), atColum3, row: 0)In my code the platform is not moving up when the PlatformLock is getting triggered by the expert.In the previous chapter with existing platforms, I do see they have the color of the PlatformLock. My ones are all the same color and I think that could be the problem, doesn't it?How can I match each Platform with its PlatformLock?Thanks your any idea :-)

I just installed Swift Playgrounds on newly installed Monterey. There is not much else installed (ie, no Xcode). The initial screens of Playgrounds seem to render properly (ie against the blue background). Then when the lesson begins the instruction and coding window appear fine, but the right panel is just a blue background with either nothing at all or a tiny little box at the top of screen that says 0/1. It seems like the animations are not rendering. I have tried to reinstall but same issues. This seems to occur in all the lessons. I have no idea where to even begin troubleshooting this and I have searched the internet and nothing similar seems to be mentioned. Suggestions?

for n in 1...5 {     print(n, terminator: "") } The output is 1 2345 The output is not "12345", as expected. Terminator doesn't work on first iteration inside a for. The error happens randomly and only on first loop. Why? Playgrounds - Version 4.0 (1567.22) on iMac 27'' 5k late 2017

Xcode 13.2 adds the Swift Playgrounds App project template that works with the upcoming version of Swift Playgrounds. The project template creates an iOS SwiftUI app. SwiftUI has a sprite view to show SpriteKit scenes so I tried adding a new SpriteKit scene to the project. Choosing File > New > File adds a Swift file to the project. The New File Assistant doesn't open. I can add an existing SpriteKit scene to the project. I can view and edit the scene. I can also show the scene in a sprite view so I know this project template supports SpriteKit. Adding an existing SpriteKit scene also adds a Resources folder to the project. When I choose to create a new file from the Resources folder, the New File Assistant opens. But SpriteKit Scene is not one of the file types I can add. How do I add a new SpriteKit scene file to a Swift Playgrounds App project?

I've been developing a Playground that works just fine on the Swift Playground app on Mac. I used the Swift Playground Author Template from Apple. Is it a Swift Playground or an Xcode Playground? I'm a bit confused given that I tested my Swift Playground on Mac, not on iPad.

All the files in my app's package add upto 7 MB. But my swiftpm package has a size of 40.7 MB! i dont get how its possible. could you please offer a workaround? Thank you! all my deliverables are done so this sucks :/

Since this year they want a .swiftpm file and it can't run on Playgrounds on mac, my submission has to be Swift Playground 4.0.2 for iPad? If I choose Xcode for Mac, will they run on debug or will they try to open it on Playgrounds (and get an error)

Hello guys! Does anyone know how to export an Xcode app project in na Swift Playgrounds' playground?

Hi there! I have a public structure and I called it in my ContentView, but I can't understand where to punt the var/let. I try to put them before "var body: some view" but it gives me these errors.
