iOS Action Extension slow loading time

So, basically I'm trying to decrease loading times for an Action Extension I'm writing for IOS.

According to: https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/ExtensionCreation.html#//apple_ref/doc/uid/TP40014214-CH5-SW7

I should aim to get the loading time below 1 second (if it takes too long it might be shut down by the system prematurely)

Right now it loads in around 4 seconds on an iPad (a bit faster in the simulator) - so far iOS haven't shut down my extension, but this will be destructive for the user experience.

As far as I'm aware I don't have access to a AppDelegate.swift file when working with extensions, thus I'm having a hard time figuring out what is causing the slow loading times.

Does anyone have any idea where to look or maybe some experience with this?

Thanks!

Solution

The reason for the slow loading times was that I launched the app extension in debug mode. Running the app without the debugger it was significantly faster.

Did not consider this at all, but now it works like a charm :)
