Xcode 27

We got a sneak peek on Xcode 27. It brings the SDK for Apple's new operation systems. We can still build our plugins with Xcode 26 and still add new features for the new operation system without using Xcode 27.

We will try the new Xcode version in the next months. But we probably won't move to the new OS before spring 2027. Somewhere in April the new macOS version 27.3 or 27.4 will ship and have most of the smaller bugs fixed.

Same for Xcode. To build the plugins with Xcode, we want to have a .1 or .2 bugfix update for Xcode itself.

Beside a lot of nice new things, Xcode 27 raises the minimum supported deployment target on macOS to macOS 11. The intel target gets deprecated. Xcode 27 comes as an Apple Silicon only application. It can still build Intel code, but by default only builds for Apple Silicon.

There is the expectation, that Xcode 28 may stop building for Intel CPU. Which may mean that we stop supporting Intel Macs at that time. If you still have one in production, consider moving off to newer hardware soon.

See Xcode 27 release notes.

AutoMutexMBS: Automatic Mutex Management in MBS Plugins 26.3

With the upcoming MBS Xojo Plugins 26.3 release, we introduce a new helper class: AutoMutexMBS. This class makes working with mutexes safer and more convenient by automatically releasing locks when an object goes out of scope.

AtomicDictionaryMBS – Thread-Safe Dictionaries for Xojo

Modern applications increasingly rely on multi-threading: background tasks, network processing, rendering pipelines, and data caching often run in parallel. In such environments, shared mutable data structures become a critical source of bugs if not properly synchronized.

With AtomicDictionaryMBS introduced in MBS Xojo Plugins 26.3, we provide a dedicated thread-safe dictionary designed specifically for safe concurrent access in Xojo applications.

Why not just use a Xojo Dictionary?

The standard Dictionary in Xojo is not thread-safe. This means:

• Concurrent reads and writes can lead to crashes
• Race conditions can overwrite data unexpectedly
• Iteration while another thread modifies data can cause exceptions
• Complex locking must be implemented manually using Mutexes

Developers typically solve this by wrapping a Dictionary in a Mutex, but this approach is error-prone:

• Locks may be forgotten for certain access paths
• Deadlocks can occur if multiple locks are used
• Fine-grained atomic operations are hard to implement correctly

MBS Xojo Conference 2026 - Protecting Sensitive Data in Xojo

We recorded the presentations at the MBS Xojo Conference in April 2026 and here is the Protecting Sensitive Data in Xojo: Practical Encryption Techniques Using MBS Plugins by Bill OKeefe.

Encryption is essential for protecting sensitive user and business data—but implementing it correctly is often confusing. In this practical session, building secure, efficient encryption workflows directly in Xojo using the MBS plugins will be shown.

Using the DICOM medical image format as a complex but relatable data model, we’ll explore how to handle mixed-type binary structures, manage endian differences, and work with Xojo’s MemoryBlock class to prepare data for encryption. From there, you’ll see real examples of AES-256 file encryption and decryption, key generation, chained encryption blocks, and performance optimization with the MBS Crypto classes.

Along the way we’ll cover common pitfalls (such as re-using IVs or ignoring data structure), when to use symmetric vs. asymmetric encryption, and how to keep your code aligned with regulatory standards such as FIPS 140 or HIPAA—even if you’re not working in medicine.

Attendees will receive a download code for working code fragments covering file, text, and database encryption techniques ready for adaptation in their own projects.

The contacts for a license

For our clients with plugin licenses for Monkeybread Software, we have a database with licenses and their email contacts.

Each license has multiple emails:

• a primary email for renewal reminders and newsletters about new versions.
• more emails as CC of licenses.
  e.g. the administrator or developer to install the license.
• older alternative emails that are marked as old.
• sometimes an extra email just for invoices.

If you contact us with one of the emails and we search the database, we find your record.

When you buy a license for a client, we can put your email as developer in our database, so all communication goes through you. We would still like to know the name of the client and use it for the license keys.

Since you may disappear and clients still may need to renew, we appreciate having the client's email in the database as an alternative one. Then we can ask them directly if they like to renew. Since we do this for 20 years, we have seen multiple developers retire already.

When you order a license for a client in the web shop, you put in the billing address. That may be either the client itself if they pay themselves or your company if you buy it for the client and bill them later. When you use your address, consider adding somewhere a few letters for indicating which customer an order applies to. Or better email us the details for the client separately. If you order an update for one of your clients, we may apply it automatically to the one where we sent the last renewal reminder.

If you already have a couple of clients with MBS Plugin licenses, you can contact us if we should change the primary email for their licenses.
