Tower 18:

But something has changed: thanks to AI coding agents like Claude Code and Codex, even the most devoted GUI fans are now spending more and more time in the terminal. You kick off a task, the agent does its thing… and then you want to actually see what happened.

That’s where Tower shines, so we felt the path from the terminal to Tower deserved a serious upgrade. With Tower 18, the Tower Command Line Tool (gittower) is no longer just a way to open a repository — it takes you to exactly the place you want to look at.

I’ve been wanting this for 15 years or so. Thanks, AI! You still can’t open a file in Tower by dragging it onto the Dock icon. Nor can you just pass it to gittower and have it figure out which repo it belongs to. But if your working directory is already within the working copy, you can now use gittower to open the file history. I’ve written a script that finds the current file in the frontmost app (BBEdit, Xcode, or Finder) and opens it in Tower.

Jared Sorge:

I know there are options out there like Paddle, FastSpring, and Lemon Squeezy that have worked for many apps like mine over the years. But I also wanted something simple for my users. Not to mention Apple Pay was a must-have.

I believe all the services he mentions do support Apple Pay.

• RevenueCat serves as the source of truth for whether or not a customer is licensed.

• I create RevenueCat customer IDs from local iCloud identifiers (more specifically, calling userRecordID() on my CKContainer in CloudKit).

• When the user makes a purchase, they earn an entitlement that I look for in Arborist to grant them a license.

He doesn’t need to run his own server, and the purchases are automatically tied to the user’s iCloud account, so there are no e-mails or serial numbers to deal with. On the other hand, well, it’s all dependent on the Apple Account.

The app, which helps manage Git worktrees, is shipping now.

Bruno Brito (release notes):

In Tower 15, we introduced the “Fully Merged” badge and Automatic Branch Management to help you keep your repository tidy. With Tower 17, we’re taking the detection behind that badge to a whole new level. […] Tower now matches your local branches against merged pull requests from your hosting service, such as GitHub or GitLab.

[…]

Trust is everything when deleting branches — so we redesigned the “Fully Merged” hint view to show you exactly which checks matched.

[…]

One that is particularly noteworthy is that updating submodules is now significantly faster! Tower gathers each submodule's Git data concurrently instead of one at a time—something you will especially notice in repositories with many submodules.

I’m sad that they got rid of the yellow icon.
