So apparently I can't test my apps on my own device without paying my Apple Developer Certificate.

I knew it is needed to pay for it if you want to publish/distribute your app but c'mon... This is ridiculous.

My app was literally a fresh app creation, a fucking white screen one page fucking app and when I tried to run in on my iPhone, then I ended up having this problem:

dyld: Library not loaded: @rpath/libswiftCore.dylib
Referenced from: /var/containers/Bundle/Application/BCD48EAA-82C2-46F6-ADEE-45C740C3B66D/HWorld.app/HWorld
Reason: no suitable image found. Did find:
/private/var/containers/Bundle/Application/BCD48EAA-82C2-46F6-ADEE-45C740C3B66D/HWorld.app/Frameworks/libswiftCore.dylib: code signing blocked mmap() of '/private/var/containers/Bundle/Application/BCD48EAA-82C2-46F6-ADEE-45C740C3B66D/HWorld.app/Frameworks/libswiftCore.dylib'
(lldb)

If any of you guys know how to solve it without paying (even more) PLEASE let me know

THANKS

Fucking linker options on Ubuntu. Somehow it seems to have --as-needed turned on by default. This leads to stripping libraries we had referenced in our target_link_libraries. Then our application won't start because of the unresolved libraries it cannot find in the Rpath, although they would be there. Thank you clever fox.
Now we have to add another stupid linker flag, just to run again.
