Now that iTunes 10.5, iOS5 and the new Xcode have been released, it is worth mentioning that to uninstall any beta installation you had, you should use the uninstaller.


sudo <Xcode>/Library/uninstall-devtools --mode=all


Where <Xcode> is the directory where you installed the beta Xcode.

I usually install the different versions into different directories (/Developer, /Developer5b3 etc).

I’ve been getting a lot of comments about how to fix the Xcode codesign failed with exit code 1; expired certificates causing ambiguous matches. This problem is such a time sink that I suspect it really helps to have someone explain the simple solution for resolving it.

To make it easier for those who’d rather hear how to solve it, I made a short video explaining the solution.

I appreciate the feedback and I’m glad to help.

And thanks to everyone who’s helped me.

I remember my friend Tom telling me about a wireless printer he was considering for use with his Canon EOS 10D camera (remember those?) At the time, I was like “But you still have to plug it in for power, which is the biggest cable.” OK, I was totally missing the point and sounded stupid while mocking “wireless”.

If you work with Xcode code signing long enough you’ll run into an error like this:

/usr/bin/codesign failed with exit code 1

If you view the build results (Build->Build Results), and expand the error message (there is a little paragraph button on the right-hand side of the line) you may see something like this:

iPhone Developer: Firstname Lastname (hashcode): ambiguous (matches "iPhone Developer: Firstname Lastname (hashcode)" in /Library/Keychains/System.keychain and "iPhone Developer: Firstname Lastname (hashcode)" in /Users/username/Library/Keychains/login.keychain)
Command /usr/bin/codesign failed with exit code 1

You have two certificates, with the same unique identifiers. One is in your login keychain and the other is in your system keychain. The real problem is, you probably have an expired certificate conflicting with your active certificate.

It has been a great week. Two iPhone apps, which I’ve been working on, went into the app store: AccelGolf: Golf GPS Rangefinder and CU24 SURF ATM finder.

I’ve only been working on AccelGolf: Golf GPS Rangefinder for a short time, but I’m having an ever-increasing role in it’s development. It’s an awesome tool for Golfers to track and improve their game. The introductory price of $4.99 is unbeatable, but won’t be available at that price for long! Find out more at AccelGolf. Or check it out in the App Store.

The SURF ATM Finder is an app I developed for a client as my own company, Whirlidoo (LLC is in the works). If you are a member of a surcharge free SURF Alliance Credit Union in Maine, you’ll appreciate this app. SURF ATM Finder is free in the App Store.
