When I press play and then stop in Xcode, my code saves to my sqlite3 database. However, when I press play and then home instead of pressing stop, it doesn't save. I had the terminal open and checked the database in deriveddata each time I tested the saving function. I don't have any code in:
(void)applicationDidEnterBackground:(UIApplication *)application
nor do I have any code in:
(void)applicationWillTerminate:(UIApplication *)application.
I save to the database directly when the user presses a button. What's the difference between the home button in the simulator and the stop button in Xcode?
Home Button will minimize your application (applicationDidEnterBackground will be called) And pressing stop button terminate your application. By quick double pressing home button you can see minimized applications by tapping one of the application icon will make your app active again from backgound state.

I developed an application with Flutter, but I have 1 problem when I test it on real devices, the keyboard does not turn off! I press the back button, it closes and reopens
when I ran my Xcode and went to type "Vatican City" in it , I typed Vatican using simulator keyboard and mistakingly typed City with my laptop keyboard.
once I pressed my laptop key , the simulator keyboard disappeared from the screen.
Now whenever I run my app and press on the UITextField, I do not get my simulator keyboard to pop up to take user input but it take input via my laptop keyboard
The properties in the attributes pane have been the same and nothing has been changed manually by me for my simulator to function like this. what should I do to get the simulator keyboard to pop up again when I want to give some user input?

Try enabling your software keyboard:
Shortcut keys: Cmd+Shift+K
This might seem like a strange question, but can I actually shut down the iPhone and restart it in the iPhone simulator? I want to do this to see if my settings are saved and reloaded when the app is relaunched AFTER shutdown.
Thanks
Yes. Press Command+Q to quit the simulator.
This will close all the apps running in the simulator.
Pressing the home button only returns to the home screen without quitting the apps(ios 4 or later) because of multitasking.
You can also double tap the home button, click and hold on the icons at the bottom of the screen till a red circle appear, and click on the red circle to close the running app.
As of XCode 9, the best way to close a single simulator is using the Cmd + W shortcut, or going to File -> Close Window.
If your'e xcode 9.You can now shutdown the simulator by long-pressing the power button.
To close/shutdown one simulated device without closing other simulations, select the device you want to shut down then go to "File" and choose "Close Window".
Now i have to click the Home button twice and press one app until the close button appear, so many steps. Is there any quick way to exit currently opened app?
You can't with the current SDK.
For some reason, when I press "Capture" while my device is connected and running the app (launched via Build & Run in Xcode), nothing happens. Never get a screenshot. iPhone OS 3.0. What can be the problem.
I've had this problem—it seems to be caused by there being a screenshot currently selected in the Organizer. Click on the left-hand screenshot pane to highlight it (i.e. deselect whatever screenshot thumbnail is selected), then hit the Capture button.
