I'm new to coding but read the Swift 3 and CocoaTouch manuals so staretd in on the Xcode tutorial.
I made through adding a Textfield, a Label, and a Button. Then connected the Button to the label and changed some text.
That's when things went sideways. On a second run, the simulator stopped executing the Button. Then the Textfield wouldn't show a keyboard.
I started several new projects and ran through the tutorial again - each time the Textfield wouldn't open the keyboard.
One of my trial projects still "sticks" on the Xcode opening screen, even though there are no associated files.
I reinstalled Xcode 3 times - no change. Upgraded to Sierra, then reinstalled Xcode again - no change. Same two problems - ghost file on open screen and no Textfield keyboard.
I have called support, developer support, and opened a TSI (cost $50). After opening the TSI I found a post that someone had an issue with the simulator so I started changing the Sumulator to different devices - it finally functioned running an iPhone 5.
I told the folks at Apple Developer Support and they said - "Glad you solved your problem!". Well my problem wasn't solved because I'm not interested in iPhone 5.
Also, I paid $50 to solve my own problem? I haven't heard from them since.
Anyone have any ideas?
I'd love to get moving on developing exciting apps, but can't seem to get Xcode to behave.
Thank you so much for your advice - This worked!
What's happening with the launch screen - I created several new projects (FoodTracker1, FoodTracker2, TestFoodTracker, etc) as I was trying to figure out the problem above. I deleted them each time and they would disappear from the launch screen. For some reason, TestFoodTracker still shows up, even though I deleted it. Clicking on the item in the launch screen gives a couple error messages. It's untidy but not a devastating issue. I included it because I wasn't sure if it was related - obviously not.
Words can't express how grateful I am for receiving both your responses - I was beginning to feel quite alone in my efforts. It's quite a relief to know there are folks out there willing to help!
