When it rains it pours
People in long lines at the Apple stores (my local store), iPhone 6 shipped today (mine is in a FedEx truck out for delivery, please hurry, we’re running out of oxygen), iPhone 6++ and its awesome camera, RubyMotion beta for Android (that is referred to as burying the lead), automatic update to Xcode 6 (thanks Apple for ruining my morning by breaking my builds), iOS 8 rollout, RubyMotion 2.3 released (minor update), Mark Rickert left his lake “house” and now is at a McDonalds in an unknown city (well I know, but you can’t make me talk), We don’t have to change our apps to Euros for Scotland. Did I miss anything?
If you missed the last issue, you can find it here: issue #43.
Happy coding, Todd Werth (@twerth)

RM Loop Efficiency
We’re all familiar (at least I assume) with ways to loop n times in Ruby.
- The universal for loop
for i in 1..n
- The terse yet readable times loop
- Finally the witty upto loop
Each loop has different readability and implementation speed. Though I’ve always had a proclivity towards
n.times do or
1.upto(n), It was my understanding that it’s generally concluded that the ugly
for loop wins. After coming across that statement again and realizing how different RubyMotion was from most other implementations, I decided to give it a go.
To my delight, the results were clearly.
for loop in RM is actually the slowest across the board! From 500, to 5 million, and there’s nearly no difference between
1.upto(n). If I had to give credence to one or the other, it seems
upto wins in Normal rake tasks, and
times wins with mode set to release.
I’m just happy all results show not to use the ugly
CDQ Tip of the Week by Gant Laborde
motion_print gem continues to sprint beyond its dead competitor
awesome_print_motion. Besides being smaller and faster, the gem hast started to support detailed printing of common RubyMotion libraries. The new 0.0.3 release can detect and elaborate on the contents of CDQ objects.
