Archived macOS app launches with blank window - xcode

I have a macOS app with a ViewController that renames and resizes the app window, has several buttons, and a WKWebView that loads a default webpage on launch.
The project itself is an .xcworkspace file, since it includes the CocoaPod SwiftSoup for HTML scraping.
The app runs great in the simulator. When it launches, it looks like this:
I want to run this app on my Mac outside of Xcode. I am not planning on releasing it to the App Store, it is just for my personal use.
I archive the project with Products > Archive, then select "Distribute App", then "Copy App" to create a directory with the archived app. This all works great.
When I launch the app, I just get an incorrectly sized blank title-less window, without the buttons or WKWebView from my Storyboard:
The app isn't hanging. I can open the "About" menu item, etc., so I know the app is running. it just doesn't seem to be using my Storyboard to draw the UI.
What would cause an archived app to differ from the app running in the simulator?
The funny thing is that I WAS able to archive this same app back in November under High Sierra, so I'm guessing the issue is either Cocoa Pods and/or Mojave related.
My debugging leads me to suspect either CocoaPods or Mojave related
My debug:
1) While debugging, I restored a version of the project from November. When I archive that restored project, I get the same blank non running app.
2) I AM able to archive another brand new project that doesn't use Cocoa Pods, so my guess is that this is either CocoaPods and/or Mojave related issue...
Any suggestions on how to proceed debugging, or help resolving this would be greatly appreciated!
I am using Xcode 10.2.1 under Mojave 10.14.5.

This problem is caused by WKWebView.
So, you need remove WKWebView from IB and then create it with code and add it to the view.

XCode Archive for app store Submission

i have several apps in the AppStore but now i am struggling with one of the apps submission.
I added to my app the chart module, and i used AMCharts for that, so to make it work, i added the AMChartLibrary project into my project, and everything works fine either usgin the simulator and the device itself for testing, and now I am ready to submit the new version to appstore and then the nightmare starts
When i run the archive to create the file to be submitted, it falls under Other Items instead iOS Apps, this disables the button "Upload to App Store", my best guess is that the AMChart library can be used for MAC and iOS apps, and for some reason the xCode organizer is not identifying it as iOS app...
I know i am missing something, but i am not finding it.
Thanks
Problem solved, i should change the skip install for the subproject under Build Settings.

Xcode storyboard showing osX object library. I want IOS object library

I develop mainly IOS apps but, recently, I worked on an OSX app. Both are possible with Xcode (I use 8, with swift).
Unfortunately, when I switched back to my already-existing IOS project (after restarting Xcode), the storyboard selection menu for the object library shows only OSX objects, not IOS (e.g. UIImageView).
I have googled without success and tried restarting Xcode, also without success. Can anyone help me fix this?
I did a lot more searching and came up with:
Xcode is loading in OS X objects instead of iOS objects
There there are other solutions proposed but the one that worked for me was to close the assistant editor and then, in the file list ( leftmost window in Xcode 8), I double clicked on the storyboard file. Problem solved. I am surprised that this bug still exists in this latest version...it is very troublesome.

How to install an app by drag-and-drop onto the Simulator window?

I have seen the following feature in the change log for Xcode 8.2
https://itunes.apple.com/us/app/xcode/id497799835?mt=12
Simulator installs an app by drag-and-drop onto the Simulator window
But I have tried drag-and-drop with .app file built for the Simulator, but nothing happens. Does anyone know how this feature is supposed to be used?
I wrote a small blog post about this.
In brief: use an .app that is built for iphonesimulator.

iOS Simulator freezes, but only on one profile

I ran into this when I tried to deploy my app to the iOS simulator earlier today - the debugger never connected, and the iOS simulator crashed. Now I can't get the simulator to do anything.
When I first launch the simulator I get a black screen (no tiles from the dashboard), and pressing the home button makes it freeze. If I access the menus at the top of the screen in OSX, that works until I press the home button, then it freezes.
Things I've tried:
Creating a new project in Xamarin Studio and running that
Creating a new project in Xcode and running that
Opening up the Xcode package contents and running the simulator .app from there
Clearing the simulator's Content and Settings.
Reinstalling Xcode fresh (5.0.2)
Pressing the home button (or whatever it's called) on the simulator
I created a new profile on OSX and running the simulator from there, and it froze for a good 20 seconds, then all of a sudden I saw the tiles appear for the home page. I then switched back to my original OSX profile, still didn't work.
The problem seems to be something with my profile, but I have no idea what to look at next. Any thoughts?
GOT IT! The problem was a file located in /Library/Application Support/iPhone Simulator/
the iPhoneSimulator folder was missing - or it looked like it was a link to a missing folder. I deleted it, ran the simulator, and it was fixed.

Xcode 5 - "iOS Simulator failed to install application" every time I switch simulators

Using Xcode 5 GM, anytime I switch to the 5.1, 6.0 or 6.1 simulators to test, I get the error "iOS Simulator failed to install application." When I reset the simulator it works, but this is getting very tiring.
Anybody have a permanent fix or workaround?
Looks like this is a known issue. From the Xcode 5 release notes:
After switching the minimum deployment target of an application from
iOS 7.0 to a release prior to iOS 7.0, building and running the
application may fail with the message “iOS Simulator failed to install
the application.”
Go to the iOS home screen, click and hold the application icon, then tap the hovering “X” button to delete the application. 13917023
Another release note:
iOS Simulator
If an iOS app is detached, relaunching the same app from Xcode will
result in a black screen in the Simulator even though the new app is
launched. Terminate the app in the Simulator or relaunch it for the
second time. 14648784
Delete the old version app in your simulator (usually iOS 6.x).
Alternatively, header over to iOS Simulator - Reset Content and Settings.
This can be easier when you have a lot of apps on the simulator and can't remember which one you're currently working on.
You need to do this for every iOS Simulator version that causes the problem.
None of the other suggestions worked for me. However, after comparing my existing app settings to a new vanilla project, I noticed that the "Build" field for my Target was blank. Once I put something in that field, the app installed just fine!
if you have already developed project and you used xib to develop views then
X-Code > Inspector Selector Bar > Interface Builder Document > opens in > and change from Xcode Default(5.o) to Xcode 4.6 .
Build and Run your app it will run successfully, if it won't run again then, header over to iOS Simulator - Reset Content and Settings. delete old app from simulator then Run again.
i got the same problem but solved by following way....
Launch the iOS Simulator
Go and click "iOS Simulator" menu
Click "Reset content and settings"
Close simulator and rebuild your app.
Above screen shot is showing the way how you can do this...
I think this works for you...!!!
Deleting the app in the simulator works for me.
just wanted to add that this happen only if I open xib that created in xcode 4.6
If it's other files, this not happen
try this ....
in my case nothing have worked for me , after resetting the content simulator also , i am not able to install the app on simulator . after that i just changed my project location . i just moved the project to other location . then it installed successfully.
None of the above things worked for me. I just reinstalled xcode and it worked.
Ran into this issue today. Found it was an empty Reference Folder (blue folder) causing this. Removed the folder from Resources in Build Phase... cleaned build folder for the heck of it, and it went away.
/Users/YOURUSERNAME/Library/Developer/Xcode/ --> remove all contents of this folder, then simply launch the app from Xcode.
To check your Executable file settng ex.$(EXECUTABLE_NAME)
(Project setting - info property page)
I have different issue when getting error message “iOS Simulator failed to install application”, the reason is because I have added a property in App-Info.plist without any value. For instance, [Application Category] with no value. Thus the error will show up as well.
When I got this error, the image of the phone actually appeared, but the image of the app I wanted to test did not. Instead, I was on the main page of the phone that shows the apps you have. I fixed this problem by deleting the many icons that appeared on the start screens - about 30 of them. These had been created when I testing apps over the months. So, not saying its a solution, but it started working after I deleted the old app images.
For me it was -framework XCTest.
It made the app die with iOS Simulator failed to install application
and on the device Could not inspect the application package.
Removed it and now works.
You are using Xcode GM which is under beta stage. Use latest Xcode 5.1.1 available.
Also, these error occur while switching between simulator (32 bit and 64 bit).
Quit the simulator and re-build the application. OR
Reset simulator from "iOS simulator" -> "Reset content and settings.."
I changed my app name and bundle id midway. I happened to delete the Executable File name in my plist. I changed it back to "${EXECUTABLE_NAME}" (no quotes) and I'm back in business.
