How to debug on a real Apple Watch

Today my Apple Watch was delivered :-)

I immediately tried to deploy my prototypes to the Apple Watch, to see how the behave on real hardware. The simulator gives only a first impression. 

Here are my learnings: Basically you need to perform two steps:

• Add the UDID of your apple watch to the developer portal
• Update your provisioning profile to support the watch

Luckily XCode can manage the whole process for you.

SWIFT 1.2

I've updated all my SWIFT tutorials to SWIFT 1.2 and XCode 6.3. You can find them here.

New Blog Domain

I've moved my blog to a new domain: developerplayground.net

Unfortunately it looks like Google has lost it's interest in Blogspot. There have been no major updates in the last two years.

I have moved my blog to a new domain. I'll continue posting links and copies of my articles also here for a while.
