iOS Build a Simple iPhone App with Swift Deploying to a Device Running on a Device

Error when building on device

I am able to run the app in the simulator but when trying to run on device I get this error. The app gets to the launch screen then this is what I see in the console. Any help would be appreciated!

Yeah me too, getting the exact same error message. Got an account and everything!

Make sure that you have signed up for a $99 per year iOS Developer Program membership, and you're logged into that account in Xcode. That's required to run the app on your device. Furthermore, if you have, you can update to the Xcode 6.2 beta and the iOS 8.2 beta as of yesterday

I have signed up and paid and logged in. That is how I am able to select my iPhone and hit run in the first place. The app loads up to the launch screen on my device but then crashes.

"dyld: Library not loaded: @rpath/libswiftCore.dylib"

I am having the same issue as Anuj. Just created an account and also signed in with it.

i'm in the exact same boat...getting the above message.

Same problem for me. Im still on mavericks, what OS are you guys on?

I'm on mavericks as well...

If that doesn't work, restart and update everything. (inc. installing Yosemite)

Hi all ive found uptrading to Yosemite fixed this for me! Cheers!

Yeah, I just upgraded to Yosemite, fixed for me too. Now let's just hope my other software works with Yosemite.
