- in other words " I'am the owner, you cannot dealloc this before aim fine with that same as retain"
- You use strong only if you need to retain the object.

What are the details of “Objective-C Literals” mentioned in the Xcode 4.4 release notes?
...st of the test is either un-searchable things like { and [, or are generic words like array , id and @implementation. The relevant keywords are literal, objc and xcode, not the specific mentions of [ or @implementation. You don't want this question to show up for general ObjC queries on Google, it s...

Why am I merging “remote-tracking branch 'origin/develop' into develop”?
...your local branch can be "fast forwarded" to the upstream branch (in other words, if it hasn't diverged).
git rebase -p @{u} effectively moves the commits you've made but haven't yet pushed on top of the upstream branch, which eliminates the need to create the silly merge commits you're trying to av...
