⚠️ This is the unsafe way to install ipa on ios, make sure the file you download is safe, don't download IPAs from fishy websites, only from devs.

Rename ipa extension to zip to extract it later

mv app.ipa app.zip

copy zip file to iphone

scp app.zip [email protected]:/User/Downloads

connect to iphone over ssh

ssh [email protected]

move to /Applications folder

cd /Applications 

Create your App.app/ directory (replace App with your app name)

mkdir App.app/ 

move to user downloads folder

cd /User/Downloads 

unzip

unzip app.zip 

the ipa contains a folder called Payload, so cd into it

cd Payload 

the payload folder contains your App.app folder, move files from this folder to the Applications/App.app/ folder

mv App.app/* /Applications/App.app/

move back

cd .. 

we don't need these files anymore

rm -rf Payload 

rm app.zip 

reset the device cache, then you can see your app on home
