Has anyone successfully compiled the "PhotoEditor: Crafting Modern Cocoa Apps" sample app recently provided by Apple? I've managed to compile it after removing several private modifiers to instance variables but once running, it performs erratically. I filed a bug report with apple a week ago and haven't gotten a response. Their sample code is usually pretty good.

I am trying to implement deep linking via this tutorial:
When i copy the first code block in, i get errors related to the declaration of
var deepLink : RemoteNotificationDeepLink?
most of which can be traced back to
Use of undeclared type 'RemoteNotificationDeepLink'.
There are no comments on the tutorial and this is the only good tutorial i have found thats not in Obj-C. Either a solution to this error or another tutorial would be much appreciated
Your issue is that you have not defined var deepLink : RemoteNotificationDeepLink? from the tutorial. That is in the second code block. All you need to do is finish the tutorial before you try and run it too see if it works. So you are trying to use it but your application does not have any context of what it is.

let me know if you are still having issues.
If you proceed to copy the remaining code blocks and follow the instructions, the solution is presented

The Apple Watch application review process seems to be getting a lot of hate recently.
I personally think we should credit Apple for dealing with a new language and a new device, but there is no excuse for not maintaining a proper list of known issues regarding Apple Watch application development.
There have been some weird solutions to some equally weird issues. I figured it was time to ask this question already.
More importantly (or less for some weird people) the Apple Developer Forums looks nowhere as great as StackOverflow.
So pick a common mistake, any common mistake.
Although an answer has been accepted, I strongly encourage WatchKit developers to share their own experiences. There's always something waiting to be screwed up.
I've rounded up some common issues here that you may find helpful: http://www.fiveminutewatchkit.com/blog/2015/4/2/submitting-your-watchkit-app
Opening an Apple Watch application project using Xcode 6.3
This might accidentally set your deployment version to iOS 8.3, which you should immediately rectify, followed by bleaching your eyes and drinking Kleenex.

I am learning the Array of swift language now but sometimes without any error in the statements, the playground of xcode does not show the result.
I've experienced that the playground is still a bit buggy. This happens to me also sometimes. What I will do then is using the println method to output or example the values of an array.

I have an iOS app which use the ffmpeg library, and iOS should compile in static link. According to the LGPLv2, do I release my source code related my UI or other bussiness logic ?
The interaction between the LGPL and Apple's app store is a disputed issue. The only way to get advice you can rely on is to ask a lawyer. I believe that you have two choices -- you can either open source your entire application or you can make available all the object code (.o and .a files) needed to re-link your application.

call-for-help: we are keep getting the illustrated error after hitting "save changes" in the application settings dashboard ... the changes are saved though ... any link where we can report our app issue?

This is not a problem with your app..
This happens sometimes because your app server might have taken a longer time to update on FB servers and the connection timed out...
Nothing to worry about you an try again
I had the same issue and solved it by checking all the icons and screenshots. I made sure that they all was in the same format (.png) and then it worked!
I guess the issue, for me, is that i used different formats.
