Interesting historical perspective (but note that with evolution as in bronze age, your iPhone with the 70's technology, would probably weight million tons…). But, the question is: did the answer proposed solve your question ?

Where do you set position of node in view ? Could you show the code, otherwise it is pretty hard to guess…

There should be a button for the user to ask to add a card. This would append a card to an array of cards And the List uses this array as data source for display. See more details (replace students by your flashCards array. https://stackoverflow.com/questions/56654877/how-to-show-list-of-views-from-a-datasource-like-uitableview-in-swiftui

Normally, Swift func signature should include the return type. OOPer gave the answer: that was a previous limit of Swift compiler. However, this should not work, as compiler is unable to resolve ambiguity: func name1() { func nest1() - Int { print("nest1") return 3 } func nest1() - String { print("nest2") return "nest1" } print(nest1()) }

Could you print values of ranA, ranB and answer ? Please report and tell what you entered in the textField @IBAction func btncheckAnswer(_ sender: Any) { print("randomA", ranA, "randomB", ranB, "answer", answer, "text", youAnswer.text) if ranA + ranB == answer { correctAnswer() } else { wrongAnswer() } }

Did you all file a bug report ? It seems to be worth it.

Thanks. Could you also file a bug report ? That could speed resolution (and please mention the FA reference here).

Size of cells of what ? CollectionView ? Can you explain the set up, what sizes you have defined ? What is the device size in for the storyboard ? What is the device target for simulator ? If you want to force cell size, you should set constraints.

So that's solved, don't forget to close the thread. That's the right practice on the forum.

You should instrument the code: if x 15000 { let z = 2 print("x=", x) } And tell what you get for x = 424

Are you sure the x you see in debugger is the x of the if statement ? May be you have declared x twice in code. Could you show more code ? Or the value you get in debugger is not captured at the same time as the one in if. Before entering 424 for x, did you enter a value over 15000 just before ? And the update of x from textField not done when test occurs ?

When do you get this error during download ? have you checked you have plenty of disk space ? And of course that your Internet connection is fast enough. Otherwise, try later at a time of low traffic (after midnight probably).

Did it work ? If so, don't forget to close the thread by marking the correct answer. Otherwise, please explain what doesn't work.

You have tried. What happened exactly ? When did it fail ? Have you checked you have enough memory available ? May be you could try first to upgrade to Majave 10.15.7 https://support.apple.com/en-us/HT211683

Why do you conclude it is an iOS bug ? Could well be an app problem. In any case, this is not a question for the developers forum. So, please go to the app developer to ask question and don't forget to close the thread. PS: Apparently you are very new to the forum. Welcome so. But please note that it is not a good practice on the forum to complain for not getting answer. Everyone here is helping on voluntary basis.
