Great summary of the most annoying Swift Playground limitations at the moment. But what the name implies - it's a playground, not Xcode on iPad yet.

Apparently only I've not written about the new Swift Playground for iPads yet...

TL;DR

- Yes, you can now build SwiftUI apps right on your iPad.
- Yes, you can use also UIKit if you prefer.
- Yes, you can ship your apps to the App Store straight from your iPad.
- Yes, it supports Swift Package Manager packages from GitHub.
- Yes, you get the fantastic new code completion, just like with Xcode.
- Yes, it ships with Swift 5.5 and all the concurrency awesomeness that entails.

FYI, be careful!

«In iOS 15 and later, the system may, depending on device conditions, prewarm your app — launch nonrunning application processes to reduce the amount of time the user waits before the app is usable. Prewarming executes an app’s launch sequence up until, but not including, when main() calls UIApplicationMain. This provides the system with an opportunity to build and cache any low-level structures it requires in anticipation of a full launch.

If your app executes code before the call to UIApplicationMain, such as in static initializers like load(), don’t make assumptions about what services and resources are available. For example, keychain items may be unavailable because their data protection policies require an unlocked device and prewarming happens even when the device is in a locked state.»

UPD
Seems like a bug, but application(_:didFinishLaunchingWithOptions:) is invoked as well during a prewarning. I've sent a link to a thread in the comments. 🤔

Hey! How are you all doing? Haven’t posted for awhile I apologize, but really burned out, tired of working stuff. So I took a vacation to finally recharge.🤞

Anyway, have you already pre-ordered a new MacBook? There are really good ones by far! I already told to the executive that it’s time to upgrade my laptop so I’m waiting for a decision… If you ruminate about an upgrading as well, there are some Xcode benchmarks with new MacBooks for help.

Interesting improvement. Starting with iOS 15 Apple extended the Codable protocol with a configuration object that gives a bit more control for the encoding and decoding processes.

I consider it's an interesting approach for fast UI development as a replacement to the Xcode playground. In my experience, SwiftUI previews are not as laggy as a playground.

p.s. Yep, previews aren't reliable as well, but... write a comment what do you think about this approach.

As we're waiting for a verdict in the "Epic vs Apple" battle, the Verge and Sean Hollister haven’t just been sitting around. They’ve been digging through a ton of internal emails and confidential presentations during the legal discovery process. Afterward, they prepared dirt on a variety of other companies as well: Microsoft, Sony, Google, Nintendo, Valve, Netflix, Hulu, and many others.


Some of my favorites in order to intrigue you:
- Apple had given Netflix a sweetheart deal where it took just 15 percent of subscriptions Netflix sold in its app (1)
- The similar subscriptions situation with Microsoft Xbox... (2)
- Apple had considered launching an ‘iPhone Nano’ (8)
- April 2013. Apple considered bringing iMessage to Android (20)
- “Don’t feature competitors in the App Store” - unwritten rule (22, 17)
...

Oh, what a surprise!

“Use switches in table rows only. Switches are intended for use in tables, such as in a list of settings that can be toggled on and off. If you need similar functionality in a toolbar or navigation bar, use a button instead, and provide two distinct icons that communicate the states.”

May your code always compile on the first try, found bugs are features actually and all projects start with iOS 15.

If you are looking forward to adopting new concurrence features in Xcode 13.2, don’t install Xcode from AppStore.

To workaround this issue, please re-download Xcode 13.2 directly from Releases section.

Amazing news! Swift concurrency is backward compatible now.

“You can now use Swift Concurrency in applications that deploy to macOS 10.15, iOS 13, tvOS 13, and watchOS 6 or newer. This support includes async/await, actors, global actors, structured concurrency, and the task APIs.”

Important to mention tip from Ole:

If you’re writing Swift concurrency code, add these compiler flags:
-Xfrontend
-warn-concurrency
-Xfrontend
-enable-actor-data-race-checks

Warnings in Swift 5.5 identify unsafe constructs, will become errors in Swift 6.
